This has been done entirely in Magic. Plan to add 3d arcitecture to give even more of a 3d walking through doorway feeling. I fucking love this program......... I will post the final video when it is finished.

As I've said before I'm not a fan of gratuitous kaleidoscope but you've integrated yours very well especially with the geometric mandala from the wallpaper - very nice touch! The 3D feel is very well executed, though when you breach the shadows the effect breaks just a little. The water reflections are great and something I've not seen before in Magic comps before - fancy doing a quick tut? Overall, the pacing and drama of this makes it an intriguing piece.
